LASTING MACHINE.

Application filedFebruary 24, 191-9. Serial No. 278,914.

To all whom it may concern:

Be it known that MATTHIAs BRooK, de-,

ceased, late of Boston, in the county of Suffolk and State of Massachusetts, invented certain Improvements in Lasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. 1

This invention relates to lasting machines, and is herein shown as embodied in a construction designed for use in machines of the general type illustrated in United States Letters Patent No. 51,018,477, granted on Feb. 27, 1912, upon an application of Matthias Brock, numerous features of the construction herein shown having been further illustrated and described in Letters. Patent No. 1,373,482 granted upon an application of Matthias Brock on April 5, 1921. It is to be understood however, that in its broader aspects the invention is not limited to machines of the type shown in said patents but is of general applicability to various types of construction. I

A feature of the invention consists in improved means for applying clamping pressure on a shoe to assist in the lasting of the shoe, the construction shown comprising a heel band and novel means for closing the band on the shoe constructed to operate with increased mechanical advantage as the pres.

sure on the shoe increases. In machines of the type illustrated in the prior patents above mentioned, the opposite ends of the heel band are connected to members which are moved lengthwise of the shoe and during their lengthwise movement are operated upon by wedging mechanism which forces them laterally toward the sides of the shoe. As embodied for example in mechanism of this type, the invention in its illustrative embodiment provides wedging devices different portions of the operative faces of which are inclined at different angles to the direction of the lengthwise movementof the members, the portions of said faces which are operative in the final application of the pressure being; more nearly parallel to said direction of movement than the portions which are operative initially to swing the members toward the shoe. This construction affords provision for a comparatively quick initial closing movement of the band followed by a slower movement with increased mechanical advantage in the final application of pressure to the shoes In the illustrative-embodiment of the invention the wedge faces.

are formed on the band closing members through the provision of curved slots in the members, the wedge faces thus having a convex contour with the portions which are operative in the final applicationof the pressure to the shoe extending more nearly lengthwise, of the shoe than the other.

portions. I

A further feature of the invention consists in novel means forrelieving clamping pres,- sure on a shoe, the construction shown comprising positive means for operating upon band closing members to force them laterally away from the shoe during their-retracting.

movement lengthwise of the shoe. Insur- 'ance'is'thus afforded that the band shall be fully open to receive another shoe, irrespective of any friction that there may be between the closing members and their supports. In the illustrative construction lateral movements of the band closingimembers both toward and from the shoe are effected by pin and slot connections between said members and a relatively fixed portion of. the struc ture, the slots beingcurved as hereinbefore explained for the purpose of increasing the effectiveness of the band closingmeans.-'

Another feature of the invention consists in novel means-for applying clamping pressure locally .on the lateral periphery of a shoe, the machine shown having a novel con-.

struction and arrangement of presser members for operating upon the heel band at the sides and rear corners ofthe heel end. portion of the shoe .to insure that the counter and the other upper materials shall be conformed closely to the lateral surface of the last. In the construction shown the presser members are operated yieldingly through toggle mechanism and pressure. equalizing connections as the bandis closed on the shoe.

Still another feature of the invention consists in novel means for rendering power driven mechanism effective to operate upon a shoe, including provision for utilizing the momentum of a driven part to perform a substantial portion of the work required in operating uponthe shoe in eachcycle of operations of the machine. In the construction herein shown, wherein the mechanism for jacking the shoe is operated through a single revolution of an operating member, provision is afforded for connecting said member to a constantly driven fly wheel of such proportions as to perform a substantial portion of the work required by reason of its own momentum. Adva'ntageously in the construction shown the fly Wheel is drivenby an electric motor which is mounted on the frame of the machine, the use of a fly wheel such as above described in connection with an individual motor drive rendering it feasible to use a motor of comparatively small horsepower, thus economizing in expense for the motor and also for the electric current. As a further provision for rendering the driving mechanism efi'ective, the construction shown includes a belt tightener which is connected to the mecha nism which actuates the clutch for connecting the fly wheel to the jacking means in such manner as to cause the belt to be tightened at the time when the work is performed, thus preventing the belt from slipping-and rendering the power of the motor fully effective in addition to the momentum of the fly wheel to insure the completion of the work on the shoe without any material decrease in the speed of rotation of the fly wheel. While this feature of the invention is illustrated as applied to the work of jacking the shoe, whereby the shoe is clamped in a heel band preparatory to the operation of heel lastin wipers, it will be understood. that in its broader aspects the invention is not limited with respect to the character of the operation performed on the shoe.

The above and other features of the invention, including also a novel construction of work support, novel means for adjusting the limit of lateral movement of the heel lasting mechanism for different styles of shoes, and various details of construction and combinations of parts will now be described with reference to the accompanying drawings and pointed out in the claims.

The machine herein shown comprises in its organization toe lasting means, heel lasting means, and means comprising a last pin 2 and a toe rest l for positioning the shoe for the toe and heel lasting operations. Since the present invention is not. particularly concerned with the character of the toe lasting means, it will suflice to state that this means comprises wipers 6 which are closed inward over the margin of the shoe bottom by the operation of a. hand lever 8, the wipers and their operating parts being supported upon a verticially movable plunger '10 which is operated by a treadle 12 to cause the wipers to effect the upwipe prior to their overwiping operation. For a more complete understanding of the construction of the toe lasting mechanism reference may be. made to the patents above referred to.

The heel lasting mechanismis mounted upon a supporting carriage 14- which is arranged to be swung adjustably for right and left shoes about a vertical pivot 16, the carriage at its rear end having rolls which travel on a curved track 18. The swinging movement of the carriage is limited by stops 20 which are mounted equidistantly from the longitudinal median line of the machine upon a right and left screw-threaded rod 22.

Turning movement of this rod, effected by mechanism which will be hereinafter described, serves to adjust the steps 20 toward and from each other to determine the limits of movement of the heel lasting mechanism properly in accordance with the swing of the last in different styles of shoes, the respective stops determining the proper positions of the mechanism for the right and left shoes of each style.

As usual in machines of the illustrative type, the heel lasting mechanism is carried by a supporting head 23 which is mounted by means of rolls 24 upon the carriage '14 for manual forward movement from an initial retracted position'to bring it into position to operate upon the shoe, where it is retained by means of a catch 25which engages a fixed lug on the carriage 14:, the catch remaining in holding position until it is lifted. by mechanism including a cross bar 26 operated during the unjacking of the shoe after the lasting operation has been completed. The heel support, includingthe last pin 2, is

the head has been moved forward and lockedby the catch 25, the heel support comprising for this purpose a block 28 slidingly mounted in the head 23 and provided with teeth 30 in engagement with a pinion 32 also mounted on the head, this pinion being operatively connected to a hand wheel 34 by which the heel support may be moved backwardly to carry. the shoe into the heel band. In connection with the hand wheel 84 there is provided locking mechanism 36 for retaining the heel support and the shoe in adjusted posit-ion, and the machine is also'provided with means including a lever 38 for automatically releasing the locking mechanism to permit relative separating movement of the shoe and the heel band after the lasting operation has been completed. I For a more detailed illustration and description of these parts reference may be made to a prior Patent No. 1,404,188 granted upon an application of Matthias Brock on Jan. 24, 1922.

In the construction shown the heel support is particularly adapted for use in lasting long legged boots, and for this purpose comprises a substantially U-shaped member 40 which may be integral with the block 28, as shown, the front arm 42 of the U-shaped member having a socket to receive and permit upward and downward movement of a spindle 44 which carries the last pin 2. In order to impart to the shoe the upward movement characteristic of machines of the illustrative type as the shoe is moved backwardly into the heel band, to position the plane of the heel seat in the desired relation to the wipers, the arm 42 of the heel support is provided with a lengthwise bore to receive a'rod 46 which engages the head of an adjustable screw 48 in the lower end of the spindle 44, the lower end of the rod 46 being operatively engaged by one arm of a lever 50, the other arm of which is connected yieldingly to ,a rod 52 slidable lengthwise in the U-shapedmember 40 and having atits upper end a roll 54 for engagement with an inclined face on a' cam member 56 which is secured on the head 23. It will be evident that as the heel support is moved rearwardly by the hand wheel 34 the rod 52 is depressed by the action of the cam 56 and through the connections above described serves to impart yieldingly upward movement to the last pin 2 and the shoe. This construction also is similar to what is shown and described in said prior Patent No. 1,404,188. As distinguished from the construction shown. in said patent, the present invention provides a construction designed to'facilitate the last-.,

ing of long legged boots the uppers of which are curved inwardly at the back near the top of the boot to approximate the shape of the wearers leg. A diflieulty has been encountered heretofore in lasting such boots due to the fact that engagementof the upperrear part of the leg of the boot with the heel support extending within it hastended to tipthe entire upper of the boot relatively to the last in such manner as to lift the heel end por tion of the upper and thus displace it andprevent perfect lasting. In order to remedy this difficult the front arm 42 of the U- shaped mem er 40 is so constructed as to provide upper and lower portions which extend in angular relation to each other, the lower portion of the arm being offset toward the left (Fig. l) in such manner as to avoid interference with the inwardly curved top portion at the back of the boot. The heel wipers 58 (Fig. 3) are mounted on carrier plates 59 connected by means of links 60 to a cross bar 62 connected at a point intermediate between its ends to a'rod 64 which is movable forwardly against the tension of a spring 66 and is operatively connected to a hand lever 68 whereby operative forward movement is imparted to the wipers. In order to cause the wipers to close inward laterally over the shoe as they are advanced,

the wiper carriers 59 are provided with slots 70 within which are positioned rolls 7 2 supported 3 independently of the carrierplates. As the carrier plates and the wipers are advanced, the rolls 72 cause the carrier plates to swingin such manner as to impart the lateral closing'movement to the wipers.

The rolls-72 are mounted on pins 74 which extend into slots 76 in a cover plate 78 see cured on the top of the lasting mechanism, and are connected by means of links 80 to a rod 82 encircled at its outer end by a spring 84 whiohbears oppositely upon the bearing through which the rod slidesand upon a collar 86 secured to the rod. The spring 84 thustends to move the rod 82 rearward-ly-in such manner as to hold the roll supporting pins 74substantially atthe rear endsof-the slots 76, provision being afforded, however, for adjustment of the normal position of the rolls by means of a 1 stop screw 88 mounted in theend of the rod 82 for engagement with a stop 90. As the wipers are advanced by the operation of the lever 68, the spring 84 tends to hold the'rod 82 and the links 80 in position to restrain the rolls 7 2 from bodily movement. In case,

however, unusual resistance to the bodily advancing movement of the wipers is encountered, as forexample where the upper stock is unusually heavy and tends" to bunch at the rear end of the heel seat, the

outwardly directed pressure of the wiper carriers on the rolls causes them to move" lengthwise of the guide slots 76 while pulling the links 80 and the rod 82forwardly against the tension of the spring 84","thus accelerating the lateral closing movement of thewipers while permitting them to close over the end oi the heel seat with a comparatively slowrate of movement. This construction allords insurance against cutting or marring the margin or the upper at the rear of the heel seat when unusual conditions such as above described are encountered.

Below the wipers 58 is mounted the heel band, the specific constrmztion 01 which is not material to the purposes of the present invention, this band in the construction shown comprising a flexible shoe engaging portion 92 molded su Jstantially to the contour f the shoe and mounted upon a support comprising a series of: pivo ally connected links 04 which maybe termed for convenience a chain. The heel band is supported at its rear end upon a yoke 96 which is adjustably mounted on the head for movement in directions laterally of the sh e to position the heel band properly for rint and left shoes the adjusting movement of the yoke being effected by means of a hand wheel, 98. At its front end the heel band is supported on levers 100 which are tulcrumed on the front ends of slide bars 102 supported on the yoke 96 and connected by means of links 104 to a cross bar 106 which is pivotally mounted. between its ends on a rod 108 movable lengthwise in the head. The rod 108 carries at its outer end a block 110 connected by a spring 112 to an operating lever 114 on a rock shaft 1 6, this shaft having last thereon a depending lever 118 which is operati'vely engaged by a plunger rod 120 to which movement is imparted by a bell crank 122 mounted on the carriage 14. The bell crank 122 carries a roll 124 which.underlies a cap 126 on a rod 128 vertically slidable on the frame of the machine and operated by mechanism to be hereinafter described. It will be understood that when the cap .126 is moved downwardly the bell crank operates the plunger rod 120 and through t levers 118' and 114 applies tension to the spring 112 to move the rod 108 and the (701% nected slide bars 102 forwardly to clamp the heel band against the shoe. The levers 100 on the ends of" the slide bars. are connected at their outer ends to springs 130 which tend to swing them in a direction to draw the onus of the heel band laterally away from the shoe and yield to permit the band to be closed inward against the shoe through the action of the slide bars 102 and also yield in response to any continued movement of the slide bars after the band has been clzunped firmly against the shoe.

Each of the slide bars 102 is provided with a curved slot 132 within which is mounted a roll 134pivotally supported on the yoke 96, this slot and roll connection causing the slide bars to swing inward toward the sides of the shoe as they are advanced to force the heel band laterally against the shoe. The curved slots 132 provide convex wedge faces 133 onthe slide bars, different portions of which are disposed in such relation to the direction of lengthwise movementof the bars as to cause a comparatively rapid initial swinging n'iove ment of the bars to close the hand against t e shoe, followed by a comparatively slow lateralniovement of the bars with increased mechanical advantage in the final application of pressure to the ends of the band. This operation willbe readily understood by reference to Fig. 5 wherein it will be seen that the portion of the wedge face 133 upon which the roll 134 isfirst effective is inclined at a greater angle to the direction of lengthwise movement 01": the bar than that portion of the face upon which the roll is effective during the final portion of the movement.

- It will be understoodthat when the cap 126 is raised, after the lasting operations have been completed, and the catch 25 is lifted to release the heellasting mechanism the spring 112 becomes effective by its reaction against the operating-connections to impart an initial impulse to the lasting mechanism to force it away from the shoe toward its normal idle position. The simultaneous release of the rod 108 and the connected parts from the tension of the spring 112 permits the springs 130 to act to swing the levers 100 outwardly from the shoe and also to move the slide bars 102 rearwardly to their initial position. During this rearward movement of the bars 102 the rolls 134 by their engagement with the inclined faces at the outer sides of the slots 132 insure that the bars shall also be swung outwardly in such manner as properly'to open the heel band -lior the reception of another shoe.

In order to apply additional pressure to the heel band at the sides and the inwardly curved rear corners of the band, the machine is' provided with side presser blocks 136 and with corner presser blocks 138, these blocks being arranged to engage the chain 94 at the sides and the rear corners of the band respectively and having inner "laces which are concavelycurved in substantially the same shape as the band. The blocks 136 are pivotally supported on rods 140 and the blocks 138 are similarly supported'on rods 142, these several rods being slidingly mounted in the supporting head. The con nections between the'blocks and the rods comprise slots in the blocks within which reduced flattened portions of the rods extend to their pivotal points, the rods presenting curved shoulders 144 which are arranged to engage the outer faces of the blocks in any position which the blocks may assume relatively to the rods, this construction'serving to relieve the pivotal connections between the blocks and the rods from any substantial strain. At their outer ends the rods 140 and 142 on each side of the ma-v chine are engaged by an equalizing lever 146 pivotally mounted on the front end of a lever 148 which is pivoted at 150 to the supporting head. The levers 148 at their rear ends are pivotally connected to links 152 which are pivoted in turn to an equaliz ing lever 154 provided with a depending pin 156 engaging in a slot 158 in an operating lever 160 pivotally mounted at 162 on a bracket 164 on the supporting head. tending loosely through the lever 160 is a rod 166 encircled by a spring 168 which bears at one end on the lever and at its other end on a tension adjusting nut 170'on the end of the rod. The rod 166 is pivotally connected at its front end to a bar 172 which is pivoted in turn to a crank arm 174 on the rock-shaft 116. It will be evident that when the shaft 116 is rocked by depression of the cap 126 in the manner hereinbefore described to close the heel band upon the shoe, I

with increased pressure against the sides andrear corners of the heel band, the levers 146 serving to equalize the pressure as between the sides and the corners of the band. lVhen the ends of the band are released in the manner hereinbefore described, the tension of the spring 168 is also relaxed to permit the pressure blocks 136 and 138 to be withdrawn to their initial positions coincidently with the opening of the band.

The operation usually termed the jacking of the shoe includes in the construction herein shown not only the application of the heel band to the shoe in the manner above described but also an elevation of the toe rest 4' to raise the toe end of the shoe into proper relation to the toe wipers and to tip the shoe backwvardlyinto the heel band as the band is closed against'the sides of'the shoe, although the term as used herein is not to be understood as limited to a combination of these different operations or restricted with respect to the precise character of the operations performed on the shoe. For elevating the toe portion of the shoe the toe rest is mounted upon a vertically movable slide 176 (Fig. 6) which carries a roll 178 engaging the periphery of a cam 180 mounted on a cam shaft182. Mounted also on the shaft 182 is a cam 184 which engages a roll 186 on a lever 188 connected by a link 190 to the lower end of the rod 128 on which the cap 126 is mounted. The shaft 182 carries also a ratchet wheel 192 provided in the construction shown with six teeth engaged by a pawl 194 on a pawl carrier 1% which is mounted to turn about the shaft 182. .It will be understood that when the ratchet wheel 192 is advanced onewsixth of a revolution by the operation of the pawl 194 one of the three projections of-the ,cam'180 is effective to raise the slide 176 and the toe rest and one of the three projections of the cam 184 is effective to operatethelever 188 in such manner as to depress the cap 126 and close the heel band on the shoe,,the machine then coming to rest with the parts in this position to permit the .operationof the toe and heel wipers, and that when the ratchet wheel 192'is advanced another sixth of a revolution the cams are rendered effec-- their normal starting positions. In the construction herein shown the pawl 194=is operated by power, the pawlcarrier 196 for this purpose being connected by means of a link 198 to a crank arm 200 fast on a normally idle shaft 202. Keyed on this" shaft and slidable lengthwise thereof is a clutch sleeve 204 (Fig. 1) which is provided with a toothed clutch face and is normally urged by a spring toward a similar toothed clutch face on the hub of a driving element or pulley 206 which normally rotates idly on the shaft 202. A rib 208 on the periphery of the clutch sleeve 204 is so disposed as to-act as a cam against which normally bears an arm 210 extending rigidly from a pivotally mounted hub 212 to hold theclutch sleeve disengaged from thep ulleyq The hub 212 has alsoextending rigidly therefrom "an arm 214 which is operatively engaged by a spring pressed arm 216to maintain the arm- 210'in clutch releasing position. Extending upwardly from the hub 212 is a crank arm218 pivotally connected to'which is arod220 arranged to be operated by pressure of the operators knee against a member 222. When the .operator presses against the member 222 the arm 210 is withdrawn from thecam 208 to permit the clutch sleeve 204 to be operatively connected to the pulley 206. The member 222 is then immediately released, and the arm 216 operating upon the arm 214 immediately returns the rear 'arin 210 into position to engage the "earn 208 and to disengage the clutch sleeve from the pulley at the end of a single revolutionin which the cams are operated to elevate the toe rest and to close the heel band on the shoe. After the lasting operation on the shoe has been completed the member 222 is again operated to render the clutch effective to impart a single revolution to the shaft 202 and the crank arm 200, whereby the cams are turned parts of the clutch are again disconnected,

substantially at the end of a single revolution of the pulley 206. In order to increase the effectiveness of the driving means and avoid any undesirable results incident to the sudden in'crease'of resistance, the pulley 206 is constructed to serve as a fly wheel, being sufficiently heavy to cause a large proportion of the work required to be done in the single revolution of the clutch to be performed by the momentum of this element. While this construction has important advantages irrespective of the character of the source of power, it is of particular advantage where the power is derived from an individual electric motor, such as 224:, which in the construction shown is mounted on a bracket 226 on the frame and is connected to the flywheel pulley 206 by a belt 228. This construction and arrangement of the parts, including provision for utilizing momentum of the member 206 to do a considerable proportion'of the work required each time that the clutch is tripped, permits the use of a motor of comparatively small horsepower, thus economizing both in the cost of the motor and in the expense for the electric current, since it is possible to use a motor much smaller than would be required if the motor alone were depended upon to overcome the sudden heavy resistance incident to the jacking of the shoe. In order further to increase the effectiveness of the driving means, the machine is provided with a belt tightening pulley 230 carried by a swinging arm 232 and connected by means of a spring 234 to a rod 236 which at its lower end is pivotally connected to a lever arm 238 rigid with the hub 212 of the clutch actuating means. When the clutch is tripped the pulley 230 is thus swung downward in such manner as to increase the tension of the driving belt 228. This affords additional insurance against any slipping of the belt when the clutch is tripped and renders the force of the motor fully effective in addition to the momentum of the pulley to assist in performing the re quired work, while avoiding strain on the parts and excessive wear of the bearings in the comparatively long periods when the motor and the pulley are running idly.

Reference has been made hereinbefore to the use of the haft 22 for adjusting the tops 20 to determine the different limits of lateral swinging movement of the heel carriage 14; for different styles of shoes. The mechanism provided for turning the shaft 22in the construction shown comprises a hand lever 240 which is mounted on the frame at the same end of the machine as the toe lasting mechanism and within convenient reach of the operator as he stands in his normal working position. The hand lever 240 is connected by gearing 242 to a shaft 244: which extends downwardly at the rear of the machine and is connected at its lower end by means of gearing 246 to the shaft 22. This construction is a substantial improvement over prior constructions in respect to convenience in effecting the required adjustment of the limiting stops.
